Insects play an important role in our natural environment. Insect collecting is a great way to identify different bugs, show them off and learn about them. Some scientists believe that bug collecting dates all the way back to prehistoric times. Humans have always been fascinated and amazed by critters and scientists are always discovering new types of bugs. There are more than 900,000 classifications, or types, of insects; so, there are always plenty to add to your collection.
